Sing_scan executes the PLC programme loaded in the PLC memory for a single scan. For all timing
events, the single scan simulates a 50 msec interval and executes all the ladder rungs as if the above
time has elapsed.
The PLC programme must be deactivated before using this command. This command is mainly used for
debugging PLC programmes and cannot be used with memory, system or programme protection on or
when the controller is in FATAL status.
Syntax: PRS
